Coupling energy storage devices on the generation side can significantly improve the AGC frequency regulation performance of thermal power units and bring frequency regulation benefits. In the traditional joint frequency regulation mode, energy storage is generally used to compensate the deviation between thermal power output and dispatching command, without considering the deep coordination between thermal power units and energy storage system. Thermal power units are still in fast variable load operation state, and the potential of coupled energy storage in improving the safety and other comprehensive performance of the units has not been explored deeply. Therefore, in this paper, the energy storage system is used to actively cooperate with the unit for secondary frequency regulation, and the load command is optimally distributed by minimizing the total cost function, including the variable load cost of the unit. The maintenance cost caused by overtemperature is considered in the cost model, and is analyzed through a simulation example. The results show that the total cost, considering the influence of over temperature on the optimal load distribution, is lower than that when the unit responds at a constant high load changing rate. The active load bearing of energy storage alleviates the cost increase caused by rapid load changing of the unit, making the unit benefit from energy storage and the total cost tends to be optimal.

Objective: To explore risk factors influencing temporary sexual behavior among gonorrhea patients in STD clinics, and to adapt gonorrhea prevention and control strategies accordingly. Methods: From August to October 2018, gonorrhea patients in 14 STD clinics across7 prefectures (cities) with high incidence of gonorrhea in Yunnan Province were screened and sampled to investigate potential risk factors. After pre-screening, a total of 179 gonorrhea patients were recruited (88.3% male).Multivariate logistic regression analysis model was performed to analyze the risk factors of temporary sexual behavior. Results: Multivariate logistic regression analysis results revealed that 55.2% of gonorrhea patients aged ≤40 years had temporary sexual behavior, 53.1% of whom had the most recent sexual intercourse were temporary sexual partners, and 53.1% were male (OR=3.765, 95%CI=1.259~11.253, P=0.018), single (OR=3.141, 95%CI=1.589~6.208, P=0.001), multiple sexual partners (≥2 persons)within the past month (OR=4.119,95%CI=1.829~9.278, P=0.001) , which were identified as the major significant risk factors for temporary sexual behavior. Conclusion: Temporary sexual behavior infection of gonorrhea patients is mainly associated with high-risk behaviors including unprotected sexual behavior and multiple sexual partners. For effective intervention and prevention, sexual education such as safe sex measurements and healthy sexual behaviors and be adopted by STD clinics and general public advocacy.

Through model verification and algorithm correction, many factors unfavorable to environmental protection existing in the production of export products abroad are analyzed. The growth trend of export trade volume of industrial industries and regions with a high degree of openness is generally consistent with the emission trend of environmental pollutants. Environmental pollution restricts China's economic growth and brings certain negative effects on China's economic growth, The relevant data analysis suggestions for improving the impact of export product production on environmental pollution are put forward.
